Add a new test where some of the packets are not passed to the AF_XDP socket and instead get a XDP_DROP verdict. This is important as it tests the recycling mechanism of the buffer pool. If a packet is not sent to the AF_XDP socket, the buffer the packet resides in is instead recycled so it can be used again without the round-trip to user space. The test introduces a new XDP program that drops every other packet. Signed-off-by:

Remove unnecessary code in the control path. This is located in the file xsk.c that was moved from libbpf when the xsk support there was deprecated. Some of the code there is not needed anymore as the selftests are only guaranteed to run on the kernel it is shipped with. Therefore, all the code that has to deal with compatibility of older kernels can be dropped and also any other function that is not of any use for the tests. Signed-off-by:

Load and attach the XDP program only once per XDP mode that is being executed. Today, the XDP program is loaded and attached for every test, then unloaded, which takes a long time on real NICs, since they have to reconfigure their HW, in contrast to veth. The test suite now completes in 21 seconds, instead of 207 seconds previously on my machine. This is a speed-up of around 10x. This is accomplished by moving the XDP loading from the worker threads to the main thread and replacing the XDP loading interfaces of xsk.c that was taken from the xsk support in libbpf, with something more explicit that is more useful for these tests. Instead, the relevant file descriptors and ifindexes are just passed down to the new functions. Signed-off-by:

Replace our own homegrown assembly store/release and load/acquire implementations with the HW agnositic atomic APIs C11 offers. This to make the code more portable, easier to read, and reduce the maintenance burden. The original code used load-acquire and store-release barriers hand-coded in assembly. Since C11, these kind of operations are offered as built-ins in gcc and llvm. The load-acquire operation prevents hoisting of non-atomic memory operations to before this operation and it corresponds to the __ATOMIC_ACQUIRE operation in the built-in atomics. The store-release operation prevents hoisting of non-atomic memory operations to after this operation and it corresponds to the __ATOMIC_RELEASE operation in the built-in atomics. Signed-off-by:

Add a new option to the test_xsk.sh script that only creates the two veth netdevs and the extra namespace, then exits without running any tests. The failed test can then be executed in the debugger without having to create the netdevs and namespace manually. For ease-of-use, the veth netdevs to use are printed so they can be copied into the debugger. Here is an example how to use it: > sudo ./test_xsk.sh -d veth10 veth11 > gdb xskxceiver In gdb: run -i veth10 -i veth11 And now the test cases can be debugged with gdb. If you want to debug the test suite on a real NIC in loopback mode, there is no need to use this feature as you already know the netdev of your NIC. Signed-off-by:

Enabling CONFIG_MODULE_ALLOW_BTF_MISMATCH is an indication that BTF mismatches are expected and module loading should proceed anyway. Logging with pr_warn() on every one of these "benign" mismatches creates unnecessary noise when many such modules are loaded. Instead, handle this case with a single log warning that BTF info may be unavailable. Mismatches also result in calls to __btf_verifier_log() via __btf_verifier_log_type() or btf_verifier_log_member(), adding several additional lines of logging per mismatched module. Add checks to these paths to skip logging for module BTF mismatches in the "allow mismatch" case. All existing logging behavior is preserved in the default CONFIG_MODULE_ALLOW_BTF_MISMATCH=n case.

When passing compiler variables like CC=$(HOSTCC) to a submake we must ensure the variable is quoted in order to handle cases where $(HOSTCC) may be multiple binaries. For example when using ccache $HOSTCC may be: "/usr/bin/ccache /usr/bin/gcc" If we pass CC without quotes like CC=$(HOSTCC) only the first "/usr/bin/ccache" part will be assigned to the CC variable which will cause an error due to dropping the "/usr/bin/gcc" part of the variable in the submake invocation. This fixes errors such as: /usr/bin/ccache: invalid option -- 'd' Signed-off-by:

Don't perform the netdev-style wait for all references when unregistering the instance. Instead the devlink instance refcount will only ensure that the memory of the instance is not freed.

Jakub Kicinski authored
The objective of exposing the devlink instance locks to drivers was to let them use these locks to prevent user space from accessing the device before it's fully initialized. This is difficult because devlink_unregister() waits for all references to be released, meaning that devlink_unregister() can't itself be called under the instance lock. To avoid this issue devlink_register() was moved after subobject registration a while ago. Unfortunately the netdev paths get a hold of the devlink instances _before_ they are registered. Ideally netdev should wait for devlink init to finish (synchronizing on the instance lock). This can't work because we don't know if the instance will _ever_ be registered (in case of failures it may not). The other option of returning an error until devlink_register() is called is unappealing (user space would get a notification netdev exist but would have to wait arbitrary amount of time before accessing some of its attributes). Weaken the guarantees of the devlink references. Holding a reference will now only guarantee that the memory of the object is around. Another way of looking at it is that the reference now protects the object not its "registered" status. Use devlink instance lock to synchronize unregistration. This implies that releasing of the "main" reference of the devlink instance moves from devlink_unregister() to devlink_free(). Reviewed-by:

Always check under the instance lock whether the devlink instance is still / already registered. This is a no-op for the most part, as the unregistration path currently waits for all references. On the init path, however, we may temporarily open up a race with netdev code, if netdevs are registered before the devlink instance. This is temporary, the next change fixes it, and this commit has been split out for the ease of review. Note that in case of iterating over sub-objects which have their own lock (regions and line cards) we assume an implicit dependency between those objects existing and devlink unregistration.

Jakub Kicinski says: ==================== devlink: code split and structured instance walk Split devlink.c into a handful of files, trying to keep the "core" code away from all the command-specific implementations. The core code has been quite scattered until now. Going forward we can consider using a source file per-subobject, I think that it's quite beneficial to newcomers (based on relative ease with which folks contribute to ethtool vs devlink). But this series doesn't split everything out, yet - partially due to backporting concerns, but mostly due to lack of time. Bulk of the netlink command handling is left in a leftover.c file. Introduce a context structure for dumps, and use it to store the devlink instance ID of the last dumped devlink instance. This means we don't have to restart the walk from 0 each time. Finally - introduce a "structured walk". A centralized dump handler in devlink/netlink.c which walks the devlink instances, deals with refcounting/locking, simplifying the per-object implementations quite a bit.

Soon we'll have to check if a devlink instance is alive after locking it. Convert to the by-instance dumping scheme to make refactoring easier. Most of the subobject code no longer has to worry about any devlink locking / lifetime rules (the only ones that still do are the two subject types which stubbornly use their own locking). Both dump and do callbacks are given a devlink instance which is already locked and good-to-access (do from the .pre_doit handler, dump from the new dump indirection). Note that we'll now check presence of an op (e.g. for sb_pool_get) under the devlink instance lock, that will soon be necessary anyway, because we don't hold refs on the driver modules so the memory in which ops live may be gone for a dead instance, after upcoming locking changes.
